James EMB 1200 Subwoofer

Has anyone listened to and can comment on the James EMB 1200 sub? Compare it to other subs in its price range ($2,200)? Obviously less when purchased used.
I have a typical FL room that's 24 X 14 with cathedral ceilings and open all the way around. Money is an issue as I will probably have to purchase two .... at some point. Any and all comments are appreciated.
Thank You
